2 Claims. (Cl. 20-55) 4 This invention relates to storm windows and tomeans for fastening such windows in position.

The present types of storm windows, if they are of the conventionalwoodenframed type, are both expensive to acquire and heavy to put up andtake down, while the metalframed, e.g. aluminum, storm windows, thoughextremely convenient, are priced beyond the reach of many.

We have devised a storm window which is very cheaply and easily made andoan in fact be made and erected by any householder possessed of a slightdegree of manual dexterity and a scintilla of ambition to doit-himself.Furthermore, since the storm windows of our invention are only a traceheavier than the glass empldyed therein, and since our fastening meansonly calls for the driving of two screws, the novel storm windows can besimply and quickly put up and taken down.

The storm window of the invention comprises a sheet of glass which is ofthe same shape as, but is of slightly greater dimensions than, theopening which is to be covered, resilient, easily compressible materialmounted at least upon the inner face of said sheet adjacent theperiphery thereof and extending substantially completely around saidsheet so as to provide a frame therefor, and fastening means secured tosaid sheet and securable to the frame of the opening which is to becovered.

The fastening means of the invention may be generally defined as aUshaped member adapted to be press- Ifitted upon an edge of the sheet ofglass and anchoring means detachably connectable to the U-shaped member.

Thus, if the householder wishes to make his ovin storm windows, he needonly order suitably sized sheets from a glazier, adhesively securestrips of resilient, compressible material around the edges of thesheet, and slip two or more (depending on the size of the window) of theU-shaped members over the edges of the sheet of glass. The storm windowis now complete and ready to be fixed in position by connecting theU-shaped members to the anchoring means.

In drawings illustrating two embodiments of the invention:

Figure 1 is a perspective view showing part of a storm window accordingto the invention, with the window about to be mounted upon the frame eta conventional window;

Figure 2 is a vertical cross-section through the centre of the fasteningmeans, showing the window of Figure 1 mounted in position upon a windowframe, and

Figure 3 is a cross-section view similar to that of Figure 2 but showinga modification wherein the strip of compressible material is appliedafter the U-shaped member has been press-fitted upon the edge of thesheet of glass.

Considerng Figures 1 and 2 in detail, first, reference character Arepresents the rectangular frame of a window opening provided with anyconventional window as indicated at B, whfle C represents a sheet ofwindow glass 2,975,491 Patented Mar. 21, 1961 which is to be employed tomake a storm window for supplementing window B in the closing of thewindow opening having the frame A. The window glass sheet C should be ofthe same shape as, but of somewhat greater dimensions than, the innerpenphery of the window fname A so that the sheet can be positioned tooverlap the outer face D for about one-half au inch (measured outwardlyfrom the inner periphery of the opening at the outer face of the frame)when laid thereagainst in alignment with the opening.

Each edge of the sheet C is provided with a strip of resilient, easilycompressible material 10 which is folded to assume a U formation inwhich it embraces the edges of the sheet, as best seen in Figure 1. Thestrips 10 are each adhesively secured to the edge which they have beenfolded to embrace. As the strips 10, we preferably employ commerciallyavailable strips of synthetic rubberlike foam such as, for example,polyurethane foam, which strips are coated along one of their sides witha pressure-sensitive adhesive. Such strips are sold with a protectivebacking strip on the adhesively coated side, which backing strip needonly be peeled ofl in order to ready the strip itself for application toa sheet of glass in the manner shown in Figure 1.

Once the strips 10 have been applied along each edge of the sheet C, thestorm windows are simply completed by press-fitting over the edgesthereof at least two U- shaped members 11 which are designed to tightlycompress the portions of the strips 10 which are straddled when theUshaped members are mounted on the edges of the sheet. For small sheetsof glass C We employ two such U-shaped members 11 mounted on oppositeedges of the sheet, at points substantially mid-way therealong, but forlarger sheets a suitably greater number of members 11 would be employed.Attached to each member 11 is a tension spring 12, to the unattached endof which is secured a cross-bar or pin 13 at a point intermediate theends of the latter.

Small plates 14 are secured to the framework A by means of screws 15.The plates 14 carry two hooked portions 16 adapted to receive and retainthe cross-bar or pin 13. Once the plates 14 have been mounted in placeit is only necessary to stretch the springs 12 and insert the bars 13within the hooked portions 16 extending from the plates 14. Once thishas been done the storm window will be mounted in position; with thewindow drawn by the springs 12 flushly against the outer face D of thewindow frame; and with the strips 11 forming an efective seal againstthe elements since, being easily compressible and resilient, they willbe compressed by any protrusions in the face of the frame but will fillin any somewhat dished or depressed regions of the face D which they mayoverlap.

The embodiment illustrated in Figure 3 is generally similar to theembodiment shown in Figures 1 and 2. However, in the case of Figure 2, aU-shaped member 11a is provided which is designed to be press-fittedover the edge of the sheet C before the strips 10 are mounted thereon.Therefore the Ushaped members 1111 should be closely complementary inshape to the edges of the sheet of glass C. We prefer to provide theedges of the sheet C, wherever one of the elements 11a is to be mounted,with a layer of adhesive tape 17 before pressfitting the members 11ainto position. Having applied the tape 17 and mounted the members 11a inposition, the strips 10 are then foldd t0 embrace the edges of the sheetC and are adhesively secured in their -edge enveloping positions alongeach edge of the sheet. The window shown inFigure 3 is mounted inexactly the same manner as the window shown in Figures 1 and 2, i.e.with the aid of springs 12, pins l3, plates 14, screws 15 and hookedportions 16 carried by the plates 14.

What we daim as our invention is:

1. A storm window assembly compising, in combination, a window opening,a window frame encompassing said window opening, 21 sheet of glasscovering said window opening, said sheet of glass having substntiadlythe same shape as but being somewhat larger than said window openingwhereby said sheet of glass extends on all sides to overlap said windowframe to a sufiicient degree to ensure safe seating of said sheet ofglass; resilient, easily compressible material mounted upon at least theinner face of and extending perpherially completely around said sheet ofglass as to provide a frame therefor; a plurality of U-shaped membersspaced around the periphery of said sheet of glass and straddling theedges thereof, the portions of said compressible materal whichnnderfiesaid U-shaped members being compressed; a plurality et plates secured tosaid window frame, a

4 tension spring attached to each of said U-shaped members, and meansfor detachably connecting said springs to said plates.

2. A storm window as defined in claim 1, wherein said means fordetachably connecting said springs to said plates comprises a barconnected to the free end of each of said springs and hooked elementsextending from said plates to receive and retain said bars.
